Astudent solved this problem and said the answer is 5 pounds.

todd has two packages of hamburger. one package weighs pound and the other weighs pound. what is the total weight of both packages of hamburger combined?

is the student's answer reasonable?

a.
yes, the answer is reasonable.

b.
no, the answer is not reasonable. it should be about 3 lb.

c.
no, the answer is not reasonable. it should be about 2 lb.

d.
no, the answer is not reasonable. it should be about 1 lb.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
